Punching without pilot hole with ALFRA PRESS AP 250 Outreach 250 mm Mobile support available as an option. 56
ALFRA PRESS AP 250 Made in Germany by ALFRA For the quick punching out of round, square, rectangular or special shapes without pre-drilling in control cabinet doors, terminal boxes, cable ducts, housings, cable guiding plates etc. up to the edge area. Tool change is easy and can be done in seconds. Description: For flexible use on a mobile frame (optional) or mounted stationary on the workbench. Quick tool change helps in case of problems with many through-hole variants. Different die holders are available also for punching right up to the edge. Punching in a row is no problem thanks to attachable fold-away stops. Tip: Use the laser pointer as an option no marking, no centre-punching, a simple cross-hair with a pen is enough. As an "entry level solution", operation by means of a manual pump is even enough for "punching without pilot drilling" at a favourable price.
